There is a 6.5-current VM running with QEMU on linux host. Usually the VM is being updated to the latest snapshot once per 10 days. Everything was OK with with 2019-04-21 snapshot. The problem has been appeared since 2019-05-01 snapshot.
The VM is installed on a dedicated drive with FDE. It is detected as sd0 by bsd.rd booted from install65.iso. But once installer is started the drive disappears.
